Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502774, here are decompositions:

13 + 31502761 = 31502774
31 + 31502743 = 31502774
73 + 31502701 = 31502774
211 + 31502563 = 31502774
241 + 31502533 = 31502774
421 + 31502353 = 31502774
463 + 31502311 = 31502774
487 + 31502287 = 31502774

Showing the first eight; more decompositions exist.
